That weird sequence is Garland's signature. He does a similar event in one of my favorite scifi movies, Sunshine.
Maybe I just like Garland's films but not his signature. If you have other recommendations I'd be interested.
Trainspotting, Slumdog Millionaire, and even 28 Days Later have related sequences.
I believe Garland has hinted he’s intending to re-adapt The Beach himself at some point.
